Subject: [PATCH for-9.0 0/4] target/riscv: add RVV CSRs
Date: Thu, 30 Nov 2023 15:27:44 -0300 [thread overview]
Message-ID: <20231130182748.1894790-1-dbarboza@ventanamicro.com> (raw)
Hi,
This series adds RVV, vstart, vl and vtype regs to the KVM driver.
But first we need a couple of things done. We need 'ptrace.h' RISC-V
linux-header to be able to read/write RVV CSRs. This is done in patch 2.
Patch 1 is the usual linux-header bump for all archs.
Patch 3 is adding a realize() callback for the KVM driver because we're
doing a prctl() to enable Vector support for the thread.
Patches are based on master. You'll need the following KVM fix to be
able to build:
[PATCH for-8.2] target/riscv/kvm: fix shadowing in kvm_riscv_(get|put)_regs_csr
Daniel Henrique Barboza (4):
linux-headers: Update to Linux v6.7-rc3
linux-headers: riscv: add ptrace.h
target/riscv/kvm: do PR_RISCV_V_SET_CONTROL during realize()
target/riscv/kvm: add RVV and Vector CSR regs
